LAMP-SOCKET.

I Specification of Batters Patent.

To all whom it may concemi v Be it known that we, RICHARD W. OSLAND andMEnIoN J. HUGGINs, citizens of the -United States, residing atPlainfield, Union county, New Jersey, and BrooklymKings county, NewYork, respectively, have incostly binding screws which would otherwlserequire tools to connect the necessary circuit wires as will be morefully described in the followin specification, set forth in the claimsan shown in the drawings, where:

Figure 1 is a perspective view of the im-' roved socket with the'capremoved. Fig. 2 is an elevation of the socket. Fig. 3 is a verticalsectional view. Fig. 4 is a side view of the metallic shell. Fig. 5 is aperspective view of the uniting key.

The body 5 of the socket is preferably made of some substantialnon-conductive material such as porcelain or glass and has a cap 6 ofsimilar material to be fitted upon the upper end of same and the two tobe locked to ether by means of a key 7 which may also e ofnon-conductive material such as vulcanized fiber but preferably of metalas the latter is stronger and as it is in no way adjacent any of themetallic connections is in consequence notliable to interfere with thefunctions 'of the socket. This key has two heads which'enter similarkeyways 7' in the'socket and the cap and holds'the two together. Thesocket has an interior .recess 8 to contain a metallic shell9 cementedtherein as usual screw threaded toy-receivethe ordinary incandescentlamp and having surface of the body 5 and through the parallel grooves17- and 18, the pins 10 and 1 1 passing up through the vertical passages16. and 19, and in the under surface of the cap ins.

,7 The electrical connection may be easily made by removing the capandlforcing the covered wire down on the pins which will perforate theinsulating fabric and make the metallic connection. The cap is thenreing key, thefeed wires being thus held in until the key is withdrawn.It; is thus"unnecessary to strip the wires of their insulae tion toinsert the bared wireunder the screw head after the manner now usual andnecessary with all lamp socketsand receptacles,

connection with the live feed wires. The

the central contact of the lamp and the cireuit is'completed throughthe'filament an the metal shell 9 and the circuit is completed the pins10 and 14. To remove the wires the key 7 is removed and the cap liftedso that the wires are freed.

making the necessary line construction the connectlons are quickly madewith means tirelyv reliable and practical.

Particular attention is called to the s ecific form or shape of the pin14, as t is form shown is absolutely necessary for accomplishing thepurpose of this socket,and also to the non-conductive washer 11, itspurpose and relative location to the other parts ofthe socket as it isabsolutely necessary as a safeguard against-short circuits. The circuitwires are shown' connected with the pins in Fig. 3. i It is obvious thatthe details of this device may be modified and otherwise arran edwithout departin tures above descri ed.

VVhat-we claim as new and desire to secure by Letters Patent is:.

a socket of non-conductive material having Patented J an. 2, 1912.Application filed May 19, 1909. Serial No. 496,897. 7 I

are two depressions 20 'for the ends of the placed and locked to thesocket by the unit-' place andonto the, pins and *not released.

through the same to the wires by means of" It will thus be seen thatthis socket is simple and substantial and while effectual in that arequickly operated, very cheap, en-

1. In a lamp socket, the combination with the pins 10'and 14extend-above the upperand at the same time providing a suitable metal.eyelet 21 makes the connection with from the essential ea,-

conductive material with a similar keyway in its lower side, a key tofit the keyways, a metallic shell for the socket and pins extend-'ingfrom the shell to the top of the socket sectin'g horizontal grooves,of a cap of similar material having depressions 'comciding with theverticalpassages of the socket, a'

key witha double head to fit similar keyways in'the socket and cap, athreaded metallic shell, a pointed pin secured to the side of the shellandpassing up one of the pas-' sages, a second pointed pm of angularform secured to the center metal eyelet of a nonconducting washer at thebottom of the shell and occupying the other passage, and a washer ofnon-conductive material to insulate the horizontal part of the secondpin from the shell.

In testimony whereof we afiix. our signatures in presence of witnesses.
